I need to find two very basic icons for a new GUI I'm building.

I want the standard power on and power off icons.

Like this

I want the off to be red, and the on to be green.
I want a transparent background ( i will be putting the icons "on top" of other buttons, so it must have a clean edge, and 100% transparent background)

I would prefer a 3d-ish look, sort of like this one:



That one there is just about perfect. However, the BG is not transparent, and I tried to edit out the background in an image editor, but the results weren't good.

Does anyone have these I can beg/borrow/steal from you?
I can resize it myself.

I prefer PNG.

I've looked through the libraries in TTD, and in some other icon collections I've put together. I'd rather not build from scratch if someone has something they can shoot me.

TIA
